I was wondering - my new 86 inch x 41 big panels have only 4 holes in the back for mounting.
While some smaller panels I have - had 6 or 8 holes
Are 4 bolt sufficient?
I can understand with front clamp mounts - yes 4 bolts are usually ok. But with the thin aluminum frame at the back - even with a substantial washer - I think that could be ripped out.
If you think that is to flimsy for high wind load - I just go ahead and drilled a couple more holes in the panels. Not really happy about it because warranty but hey - when they fly away, warranty doesn't cover it either.
